GAS-PRESSURE REGULATOR.

-To all whom/ may concern.:

-My object is to gases 'which have a .is/'adapted m nection with t5 invention co gulators,

uexed.

It is constructed ing had to the Which- Figure l is a vertical s e regulator, show 5 parts when the pre SSUFG ator are inclosed -pa-rts a. and a', adapted gether in ner, shown, the lower end, as shown a the regulator is ordinary way. of the part b an flowing part a be d over the gas is ya centra phragm c, having a tub mounted around the centr diaphragm c.

ection with thevaceolnis a full, clear, and exact elates to gas-pressu re reguproduee a regulator for u. irregular pressure and ore particularl gas-stoves; and to that end nsists in the severalV new as follows, reference beaccompanying drawings, in

ing the position of the pathway of t p plan view the Ire when. desired. f refere: ce indio? .e correany ordinary and wellpret'erably by a ser t b, and threa secured to the Mounted withi EPH HENRY of which the foly for use in con` my and ctional elevation of he iniiowing gas. reot'. Fig. 5-isa Fig. 6 is atop plan an elevatioi of a ng the ow ot' gas th parts forming and comprises two to be secured toknown manew and thread, as ing open at its lower ded, by which gas-pipe in the n the recess bpathway of the inlly-perforated diaular valve-seat c 994. (No model.)

perforated as shown at d and mounted loosely within the casing above the y diaphragm c and is provided with a dowuwardly-extending pine, having a balanced 55 valve e', adapted to fitloo'sely within the tubular valve-seat c', The upper side of the valve is provided centrally with a post f, the upper end being centrally recessed, as shown at f', and provided with transverse openings 6o g opening into the interior ofthe casting A. The upper end of the post f enters the upper exit g of the easing, 7L being-the exit-pipe` connecting therewith.

D is a thumb-screw per end of the aperture in the casing and having a downwardly-extending shank J1.' adapted to engage with the post f to force it downward when the regulator is under high pressure for the purpose of aifordin g a greater 7o ow of gas when desired.

The operation of the regulator is as for# lows: The gas passes up through the aperture b,and thence through the aperture c' in the collar c, and thence through the diaphragm into the interior of the regulator, thence, when the pressure is low, up through the apertures d, and thence Cut through the portsf up into the exits g 7L. When the press- C is a piston,

upward, as'shown in Fig.V 2, which causes the enlarged end e of the pin e io be drawn up opposite to the apertures c', and thus retard the inflow of gas. At the same time the apertures f in the post f are forced up into the 85 lower end of the upwardly-extending pipe g and thus further assist in retarding the flow l of gas through the exit.

l'Vhen the pressure forces the balanced valve up, as shown in Fig. 2, in oase I desire to allow a greater pressure I force the shank h against the post f,forcing the end c out ofengagement with the inlet-ports c', which will permit of a greater pressure. .l

E is a spiral springlnounted upon the post f, having its lower end resting upon the bal- A anced valve and its vupper end adapted to engage with thev top of the inner wall ot' the casing A for the purpose of producing an even pressure where t pressure is spasmodic.

a1 opening B in the Having described my invention, what I engaging with the 11p-'465 n ure is heavy the-balanced valve C is forced So y he supply or natural roo claim, and desire to secure by Letters Patent, is-

1. A gas regulatorbomprising a valve'casling having a suitable inlet and an upper" exit, a perforated diaphragm having'a transversely perforated valve seat mounted wit-hin the lower portion of'the casing, a perforated piston mounted above said diaphragm and having a @Qwnwardly extending pinor. valve adapted to passinto the valve seat on the diaphragm and a post extending up into the upper exit,i perforated transversely, as s et forth.

" 2. A gas regulator comprising a valve casing, havinga suitahleinletandan upper exit,

in g up into theupper exit recessed and perrorated transversely and a thumb screw D- as set forth.

3. A gas regulator comprising-a 'valve casing, having a suitableinlet an upperexit, a perforated diaphragm 'located within the lower port-ion of the casing and lprovided with a valve seat as described, a perforated pistou mounted above said diaphragm and having a downwardly extending pin`elarged to form a valve, and a post extending u pinto the upper exit, recessed at its upper end and perforated transversely, and a spiral' spring mounted upon said post, engaging the upper face of the piston'and the upper Wall of the @asin g and a thumb screw D., as set forth.

, In witness whereof I have hereunto set my hand on this ll-th dayl of March, 1895.
